He lives, then, on ginger-nuts, thought I; never eats a dinner, properly speaking; he must be a vegetarian then; but no; he never eats even vegetables, he eats nothing but ginger-nuts. My mind then ran on in reveries concerning the probable effects upon the human constitution of living entirely on ginger-nuts.
~ Bartleby, the Scrivener by Herman Melville

Up to a certain point the thought or sight of misery enlists our best affections; but, in certain special cases, beyond that point it does not. They err who would assert that invariably this is owing to the inherent selfishness of the human heart. It rather proceeds from a certain hopelessness of remedying excessive and organic ill.
